My invention relates to certain improvements in machines for baling hay, straw, cotton, excelsior, and the like; and my invention consists in features of novelty hereinafA ter fully described, and pointed out in the claims.

Referring to the drawings, 1 represents the baling-chamber, the forward end of which is provided with a feed-hopper or extension 2.

3 represents the traverser or plunger as a whole.

4 represents the pitman.

5 represents the reach; 6, the front axle; 7, the wheels of the front axle, and S the wheels of the rear axle 9.

The reach 5 extends from the forward end of the baling-chamber to the front axle G, to which it is secured by a vertical shaft or spindle 1Q. The end of the reach fits in an opening 11 of the front axle, as shown in Fig. XXIV, and the shaft or spindle passing through it allows the axle to turn on the reach in transporting the machine from one place to another. This end of the reach is shown in detail in Fig. XXVIII, and here the shaft is also shown in section. The reach has preferably an inner box 12 and an outer box 13, held by straps or strips of metal 14, secured to the reach, a bolt 15 passing through the outer edges of the straps and the outer box 13. The shaft or spindle is best shown in Fig. XXV, the lower end 16 being the part that passes through the front axle and through the reach. On the shaft, above the end 16, is rigidly secured a trip-lever 17, that has rounded ends 1S. Between this lever 17 and the front axle a crank-arm 19 is loosely mounted on the shaft. This is best shown in Fig. XXVI. To the outer end of this arm the pitman a is secured, preferably by means of a sleeve 20, securely clamped to the pitman, and which has a projection 21 fitting in a perforation in the outer end of the arm and held thereto by means of a bolt 22 and washer23. (See Fig. XXVII.)

24 represents an antifriction roller j ournaled by means of a pin 25 in the sleeve 20. The anti-friction roller 24: is located in the VIOO path of the outer ends of the lever 17, so that4 as the shaft l revolves the rounded ends 18 of the lever 417 come against the roller, as

pitman reaches a straight line from the traverser to the pivot of the arm 19, and as soon as the ends of the triplever pass the end of the pitman the traverser rebounds, the arm and pitmancoming back into the position shown in Fig. II, thus always rebounding on the same side of the press.

The press is what is called a full-circle press-that is, the draft-animals pass around by screws or bolts 31.

a complete circle. When the traverser has thus been forced forward by the Contact of one of the ends of the trip-lever with the pitman, and this end of the lever leaves the pitln-an, tl1e`traverser will rebound and the animals continuing round on the circle bring the other end of the trip-lever into engagement with the pitman, and the traverser is again forced forward to compress another charge, and in this way two charges are pressed at each complete round of the sweep.

27 represents the sweep. It is connected by its inner ends to a cross-head 28, (rigidly secured to or formed in one part withy the upper end ofthe shaft 10,) by means of sockets or sleeves 29, which receive the ends of the sweep, and which tit over reduced ends 30 of the cross-head 28 and are held loosely thereon The cross-head is best shown in Fig. XXV, and the sleeves (which are not shown in Fig. XXV) are best shown in Figs. I,JII, and XXIV. The outer end of the sweep is supported by means of a rod 32, which extends from Aa cross-piece 33 back through a slot 34 in a projection 35 on-the cross-head 28. The rod .32 and cross-piece 33 are best shown in Figs. I and II, and the slotted projection 25 in Figs.- XXIV and XXV. The outer end of the rod 32 has upon it a nut 36. By tightening this nut the outer end of the sweep may be raised, and by loosening the nut the outer end of the sweep may be lowered, the sleeves 29 turning on the cross-head. Vhile this rod limits the downward movement of the outer end of the sweep, it does not prevent the upward movement in case, duringtransportation, the wheels of the press should pass into ruts, and thus the strain is relieved from the necks of the animals.

It will be understood that the set-screws 3l", while they hold the sleeves 29 on the crosshead, still do not prevent the turning of the sleeves in a vertical plane.

'51. -gagement with the notch "for groove in the y shaft the latter is thus prevented from turnalways faces the forward end of the sweep.

39 represents the draft-tongue, and 40 the single and double trees by which the animals4 are connected to the sweep in operating the press. By the use of the tongue (which, of course, would be supplied with the usual neck-yoke) the sweep is prevented from being thrown against the animals by the rebound of the plunger, as any tendency of `this kind is received by the necks of the animals through the usual connection of the neck-yoke.

When the machine is in operation, the shaft l0 turns loosely in its lower bearing with the front axle 6 and its upper bearing, which consists of a box 4l, mounted by curved arms 42, (see Figs. I and XXIV,) which connect the box to the front axle. The box is bolted to the upper ends of the arms 42 at 43, and it ts on the shaft 10 directly over the triplever 17.

44 represents a circular track which supports the outer end of the crank-armY 19, as

shown at 45, Fig. XXIV, and the ends of this track are secured at 46 to the arms 42. (See Figs. I, XXIV, and XXVI.) They are thus connected 4by a bolt 47, passing through the ends of the track, through the arms 42, and through a sleeve 48, placed between the arms. The sleeve is provided with perforated lugs 49, to which the single andy double tree 40 is connected when the machine is to be moved from one place to another. When the IOO machine is thus moved, the sweep is utilized p as a tongue, (the tongue proper 39 at this time being turned back into line with the sweep,

` so as to be out of the way,) and it will benecf essary to provide some means to prevent the sweep turning on the shaft 10 during transportation. As a means to prevent this, Iprefer to employ a dog or block 50, which is pivoted to ears or projections 51 on the box 41.

The shaft 10 is provided with a notch or groove 52, which (when the sweep is in line with the body of the machine and projecting* away from the machine) is opposite the ears By throwing the block 50 over into ening relatively to the box, (which means also relatively to the front axle, as the box is connected to this axle,) and thus the sweep is rigidly connected to the front axle and is utilized as a guide-tongue.

The dog 50 and its operation are best illusA trated in Figs. XXI and XXII.

3, as stated, represents the traverser secured to the inner end of the pitman 4. Its construction is best shown or illustrated in Figs.

. VIII and IX. It is provided at bottom with anti-friction rollers 54, that bear on the bottom of the balingm'hamber to relieve the friction. To its upper'side is secured amovable tro plate or cross-piece 55, having downwardlyextending ears or projections 56, which have slot 57 and pin 57 connecting with the traverser. The normal position of this plate or cross-piece is shown in Fig. IX, where it is held by springs 58, secured to the traverser and bearing against the under side of the ears 56. The plate extends entirely across the traverser, asshowny in Fig. IV, and the ears or projections 56 are secured at or near the respective ends to the plate. (See Fig. VII.) There is a spring 58 beneath each ear or projection. This is also shown in Fig. IV.

The object of the plate 55 is to form ayielding top to the traverser to prevent its severe binding(caused by part of the material getting between the top of the traverser' and the upper wall of the baling-chamber.) It will be understoodthat in baling-presses the material which is fed into the baling-chaniber when the traverser is in its rear position very frequently extends slightly into the feedinghopper, and thus a portion of the material is liable to, and nearly always does, get between the top of the traverser and the top of the baling-chamber, thus causing a great deal of friction and resulting sometimes in the breakage of the press. My object is to construct a traverser which will have a yielding portion at top to avoid these difficulties.

The normal position of the plate 55, as stated, is that shown in Fig. IX. When the traverser is forced forward beyond the feedhopper, this plate is compressed toward the position shown in Fig. VIII, but will be only so far compressed as the amount of material between it and the top of the baling-chamber necessitates. The springs 58 yield under this pressure, but are of sufficient force to hold the plate supported at all other times. It will thus be seen that the traverser will yield to this pressure of the material and avoid much unnecessary friction, and also avoid danger of breaking the press. When the traverser reoedes, the portion of the material which thus overhangs the top of the traverser is left in the position shown in Figs. IX and X, and it will be forced in in advance of the next charge. For the purpose of folding this material down upon the withdrawal of the traverser, I employ a plate or block 60, which is connected at its lower end by links 6l to a rod 62, th at extends across t-he machine. This rod andthe links are shown plainly in Figs. VI and VIII. The plate is connected at its upper end to the rear end of the hopper by means of a short bolt 63, having a nut 64 and a washer 65. The hole in the hopper through which the bolt passes is elongated sufficiently to allow the plate to rise and fall. As the traverser. comes forward the plate 55 comes against the inclined end 66 of the plate, and lifting the plate passes it. By

` lthe time the traverser recedes this plate has fallen again, and the plate 55 will in passing the plate 60 turn, as shown in Fig. X,.and

The plate 55 is preferably provided with a sharp cutting-edge 67 at its top. The object of this is that if there is too much pressure between the traverser and the top of the baling-chamber when the plate has been forced downward tothe limit of its movement this material will be cut by the sharp edge, and thus avoid friction and danger of breaking the press in these unusual instances.

For the' purpose of condensing the material in the hopper before it falls into the balingchamber, I use a plate or disk 68. This is connected to the hopper by a box 69 ona rod 70 fitting in slots 7l inthe sides of the press. The ends of the rod outside the hopper are provided with friction-rollers 7 O, bearing on tracks 701), secured'to the hopper. (See Figs. I and III.) These relieve the plate of friction.

72 represents an arm secured to the plate, to the outer end of which is connected a lever or rod 7 3. The lower end of this lever is slotted, as shown at 7e in Figs. VIII and IX. Through this slot passes a rod 75 fitting in the walls of the 'Daling-chamber. Thelcwer end of the lever is formed with an opening 76, as shown in Figs. IV and IX.

On the traverser is a plate 77. .lust before reaching the limit of its backward movement the plate 77 passes into the opening 76 inthe lower end of the lever 7 3, and a lug 78 .on the traverser just beneath the plate 77 comes against the lower end of the lever and forces the lever in an outward and upward direction, the slot 74: moving over the rod 75. This brings the plate 68 from the inclined position shown in Fig. VIII to a vertical position and then moves the plate forward from the position shown in Fig. VIII to the position shown in Fig. IX, thus condensing the material in the hopper. Vhen the traverser moves forward again, the plate 68 will be drawn back to the position shown in Fig. VIII (from the position shown in Fig. IX) by the friction between the lower end of the lever 7 3 and the pitman 4, the lever resting on the pitman, as shown in Fig. IX. In this manner I produce an automatic device for condensing the material in the hopper before it passes into the press, the device being inexpensive and not liable to get out of order.

As the material is condensed on the backward movement of the traverser, it is of course necessary to have some means that will prevent the material from falling into the baling-chamber behind the traverser. To accomplish this I use atlexible apron 80. The forward end of this apron is connected to the plate 55, or to the upper end of the traverser, and its inner end is secured to a spring-drum or windlass 8l. (See Figs. VIII, IX, XII, and XIII.) As the traverser moves forward the apron is unwound from the drum, and then as the traverser recedes the apron is wound again upon the drum. When the traverser the material extending, as described, is tucked down into the chamber by the plate 60.

IOO

i and supports the material until is in its forward position, as shown in Fig; VIII, the apron forms a bottom to the hopper the traverser recedes.

Mypreferred manner of constructing the drum is to form a cylinder to which the apron is secured, and which surrounds a central spindle 82. 0n the spindle 82 a spiral spring 83 is wound. One end of this spring is connected to the spindle and the other to the cylinder, preferably by means of a plug 84, (see Figs. XIII and XVI,) the plug having a projection 85 fitting in a notch 86 of the cylinder (see Fig. XV) and having a hole 87, into which one end of the spring is inserted, as shown in Fig. XIII. The plug 84: fits loosely on the shaft or spindle 82. The shaft or spindle has a square portion 88 extending beyond the wall of the press, and it is supported by iitting in holes made in the sides of the baling-chamber. Over this end 88 is fitted aplate 89,which is secured by a bolt 90 to the balingchamber. This plate prevents the turning of the shaft or spindle, but does not prevent the turning of Iheouter cylinder 81. It' additional tension is'necessary, the plate 89 can be removed byremoving the bolt 90, and then by turning on the spindle (by a crank or key applied to its non-circular portion 88) in the proper direction the spring can be tightened, andvthen by reapplyin g the plate 89 thespindle will be held from being turned by the spring. The spring-apron, besides serving the function of forming a temporary bottom to the hopper, also serves as an additional means or force for causing the rebound of the traverser.

As a means for preventing the material expanding in the baling-chamber beneath the feed-hopper on the return of theftraverser, I pivot a number of plates or dogs 91 to the side of the baling-chamber, (see Figs. IV and VL) which are inclosed by a casing 92. The forward ends of these plates are provided with points 93, that enter slots 94 in thesides of the baling-chamber, and they are forced into the baling-chamber a short distance by springs 95, fitting in sockets 96, made in the housing 92. The front faces of the points 93 are tapering, as shown at 97, Fig. IV, so that as the material is forced forward the points will be forced out of the baling-chamber against the pressure of the springs 95, and when the material has passed the springs will force them in again to prevent the material following back, as shown in Fig. VI, I do not broadly claim these pivoted plates, as I know that dogs or plates have been used for this purpose in baling-presses.

represents a rod extending" from the box 41 to the baling-chamber, to which it is secured, as shown at 101, by means' of a crosspiece 102. This cross-piece is shown in Figs. I and IX. The object of this rod is to form a bond between the shaft 10 and the balingchamber, to add strength to the shaft, and it lalso affords a means of attaching a guardthe animals cross the operated.

represents an arm connecting the rod to the reach 5. This is best illustrated in Fig. XX, where the pitman and plate 103 are also plainly shown. The outer end of the rod 100 is connected to the box 41 by means of a yoke 106, passing around the box and through lugs 107 thereon. This yoke also serves to connect the two parts ofthe box together. Between the lugs the box has a socket 108, through which the end of the lrod 100 passes and is held by a nut 109. (See Fig. XXI.)

As a means for retarding the movement through the press of the material being baled, and thus to regulate its density, I employ friction-blocks 110. These are best shown in Figs. XVII, XVIII, and XIX. They are supported onvertical rods 111, fitting in slots 112 on the plates, or in projections 113 on the plates. rlhe blocks lit on the respective sides of the baling-chamber, and it will be seen that by adjusting them inwardly or outwardly the delivery of the material will be more or less free. As a means for adjusting them,I secure aframe 114 on each side of the press, and to the center of this frame pieces pitman las the press is 115 are secured, as shown in Figs. XVII and4 XIX.

116 represents threaded rods stepped or iitted at their outer ends in pieces 115 and entering the sockets of the projections 113 of the blocks 110. On the rods are hand-wheels 117. It will thus be seen that by turning the rods by means of the hand-wheels the blocks 110 may be adjusted in and out at will, as stated.

Before using a press it is generally desirable to remove the hind wheels and let the rear end of the press down upon a fixed or substantial support. For the purpose of accomplishingthis I secure curved arms or bars 120 to the rear axle or to the frame of the press. I connect their lower ends by chains 121 to the frame of the press. The upper ends of the arms or bars are slotted to receive levers 122. Thus when the wheels are to be removed the arms or bars are thrown down into contact with the ground and the animals started. This will cause the wheels to be lifted off the ground, as shown in Fig. XXIII, the chains serving the purpose of preventing .as shown in Fig. I, and it is located where j IOO IIO

the lower ends of the arms or bars passing behind their pivots, so that the machine Willbe supported while the wheels are being removed. Then by taking hold of the levers 122 and moving them in the direction indicated bythe arrows in Fig. XXIII the machine may be lowered. The arms or bars may also be used for the purpose of elevating the machine again to apply the wheels.
